separately excited, dc motor has the following name plate ratings:

Terminal voltage = 400 V Speed = 1250 rpm Developed torque at full load = 90 Nm Full-load armature current = 30 A A single-phase, full-wave, ac/dc converter is connected between a 480 V (rms) ac source and the armature terminals. A fan-type load is connected to the motor. When the triggering angle is adjusted to 40o, the motor speed is 1050 rpm. Calculate the triggering angle required to operate the motor at 1200 rpm. Assume that the armature current is always continuous.
